WASHINGTON, D.C. - Landing a trip to space might be out of sight, but it could mean losing your sight! A mysterious syndrome might cause astronauts to go blind. It has taken rocket scientists to figure this one out!
NASA claims zero gravity in space has led to "inter-cranial pressure syndrome." That means extra fluids in the skull increases pressure on the brain and flattens the eyeballs!
Things have gotten so bad in the past that two-thirds of astronauts have returned to earth with poor eyesight!
Back in 2005, award-winning spaceman John Phillips blasted off with 20/20 vision and six months later he came back down to earth with a 20/100 vision!
Bet he didn't see that coming!
